What is an example skill within the Number Sense and Operations category?

• A. Solving equations with variables
• B. Comparing absolute values and multiplying/dividing multidigit numbers with decimals.
• C. Interpreting graphs
• D. Understanding geometric proofs

Answer: (B)

Number Sense and Operations focuses on understanding numbers, their sizes, and how to compute with them, including place value, decimals, and basic arithmetic reasoning. An example skill in this area is comparing absolute values and multiplying/dividing multidigit numbers with decimals.

Comparing absolute values means judging how far numbers are from zero, regardless of sign, which sharpens sense of magnitude and order on the number line. Multiplying or dividing multidigit decimal numbers reinforces decimal place value and careful alignment of decimal points. Together, these tasks show fluency with both the size of numbers and the operations you perform on them.

The other options belong to different math areas: solving equations with variables is algebra, interpreting graphs is data/graph reading, and understanding geometric proofs is geometry.
